【参考答案】

III. 1. A. 这是一道细节题。由It can swim, turn and dive like a real shark. 可知，仿生鲨鱼能像真正的鲨鱼一样移动。故选A。

原文中提到的 The 4.7-meter-long “shark” has mechanical fins. 不能推断出仿生鲨鱼比真正的鲨鱼大；它的功能里也并没有提到吓到游客，故B、C都不对。

2. B. 由文中细节信息可知仿生鱼几乎没有噪音，所以不易被声波定位仪发现。同时与反潜艇飞机相比，仿生鱼更成本低，工作效率高。

3. B. 本题也属于事实细节题，由文中细节信息可知仿生鱼能够在沉船里面或者周围游动，给人们发送各种数据。Smaller robots can swim in and around sunken ships, sending all kinds of data back to people.

4. D. 本题属于大意概括题。由最后一段内容可知我们研发仿生鱼的目的还有了解更多关于鱼的行为to learn more about fish behavior and what it’s like to get eaten by sharks!
